THREAD-PARTING MECHANISM FOR FILLING-REPLENISHING LOOMS.

Application filed July 3, 1906.

To all whom it may concern:

lle it known that I, FRANCIS A. Mints, a. citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented an lmprovement in 'Ihread-Parting Mechanism for Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a speci fication, like letters on the drawings repre senting like parts.

This invention relates primarily" to filling replenishing looms, although certain features thereof are not restricted to a filling replenishing loom.

I have chosen to represent my improvements applied to a filling replenishing loom of the type wherein the bobbinis replenished upon substantial exhaustion of filling in the running shuttle but I wish it to be clearly understood that it is within the scope of my invention to employ a filling replenishing mechanism wherein a fresh shuttle, having a. supply of filling therein, is substituted for the running shuttle either upon substantial exhaustion or upon filling failure, or that I may employ weft carriers or cases within a shuttle, a weft carrier or case being ejected from the running shuttle and another substituted therefor upon substantial exhaustion of the filling or upon colnpletc failure thereof.

It is also within the scope of my invention to employ a bobbin replenishing loom operative upon the entire absence of filling instead or upon substantial exhaustion thereof.

Inasmuch as these several types of filling replenishing mechanisms are well-known, it is unnecessary for me to illustrate more than the mile type shown, which, as before stated, presents merely one practical cmhodiment of my invention.

My invention particularly relates to means for severing or cutting the filling pertaining to the bobbin that is to be ejected, if this type of replenishing mechanism be employed, and to means for severing or cutting the filling pertaining to the new bobbin with which the shuttle is replenished in this type of re plrnishing mechanism. \Vhile I employ the same severing evice to sever the old and the new filling, in certain asper of my inventi n I am not limited to employr-ohi oi the ame device to sever both fillspecification of Letters Patent.

ings, nor am I limited in certain aspects of my invention to any location of such severing device, although I preferably mount the same upon the lay of the loom and preferably in the rear of the reed, or in the rear of the plane of the front face of the reed, that is to say, in the rear'of the path of the shuttle.

While the specific embodiment of thread severing means here shown is a threadcut-r ter, I am not limited thereto, as any other type of thread severing mechanism may be employed so far as certain features are concerned. I have also chosen to illustrate my invention as pertaining to that type of loom wherein a weft fork or filling indicator is employed upon each side of the loom and I have chosen in -ertain aspects of my invention to employ he auxiliary Weft fork (being that weft o"k which is upon the replenishing side of the loom) to operate the cutter or filling scve mg means under certain conditions, but in other aspects of my invention I am not lim ted to the use of such auxiliary weft fork or fillin indicator.

A primary feature of mv in ention is to so sever the old and the new filling, or either of them, essentially at the selvage, that after the severance of said ends the end of the filling contained within the fabric is not exposed or is not essentially exposed beyond the selvage.

I am enabled by my invention to dispense with the retrimming of the fabric produced in weft replenishing looms which heretofore it has been impossible to dispense with, owing to the fact that the filling was severed at such a distance from the selvage that the latter presented an unsightly appearance. I am also enabled to prevent the formation of slugs, caused by the drawing into the shed on the succeeding pick, of the short end of the old or new filling that was cut at a substantial distance beyond the selvage.

In the drawings: Figure 1 is a plan showing'that side of the loom wherein substan tial exhaustion of the filling is indicated, the parts being represented. in the indicating posltion; Fig. 2 is a plan showing a portion of the opposite or replenishment side of the loom with the arts in position to cut the old filling that is to be ejected; Fig. 3 is a plan on an enlarged scale of a portion of tha side of the loom whereat replenishment occurs, the parts bein in the position to sever the new filling; Fig. 4 is a detail showing the severing of the filling; Fig. 5 is a plan of a portion of a loom at the filling re plenishing side thereof, showing the normal running position; Fig. 6 is a cross section through the lay, showing the cutter in its normal or inoperative position, many of the parts being shown in elevation; Fig. 7/is a vertical section through the loom from front to rear, on line 7-7 of Fig. 2 looking to the left, showing the cutter in readiness to cut; Fig. 8 is a detail showing in plan the trans fer shaft of the replenishing mechanism and the cutter operating means connected therewith; Fig. 9 is a cross section through the lay representing the cutter as having just severed a thread; Fig. 10 is a detail of the operating levers for the cutter and connected parts, upon the line 1Q--10 of Fig. 9; Fig. 11 is a cross section upon the line 11 11 ofFig. 1, looking to the left and representin the indication as having just occurre Fig. 12 is a detail upon the line 12- 12 of Fig. 1; Fig. 13 is a vertical section of the loom, on line 77 of Fig. 2 looking to the right, showing a portion of the hopper of the weft replenishing mechanism and the position of the filling with relation to the running parts of the loom; Fig. 14 is a cross section of the shuttle box and shuttle showing the thread guide or holder and the cut out or recessed wall of the shuttle box, such section being taken on the line 14-14 of Fig. 2, looking to the right; F i 15 is a similar view upon a smaller scale, ut showing the binder at the front and recessed or cut away; and Fi 16 is a detail showing inverted a part 0 the shuttle box wall or binder as the case may be having a portion thereof recessed or cut away.

. Referring more particularly to Figs. Land 2, in the drawings: 1 indicates a shuttle of any preferred type, having a bobbin 1 therein; 2 represents the pickers; 3 represents the shuttle guards; 4 represents the shuttle base plate; 5 represents the shuttle binders; and 6 represents the feeler of any desired type adapted to feel within the shuttle and to indicate substantial exhaustion thereof in any preferred manner. 7 indicates a portion of the feeler adapted, when substantial exhaustion occurs, to impinge upon the lever 8 (preferably spring pressed), pivoted at 9, and to move the same outwardly or to the right, viewing Fig. 12, to thereby depress the adjacent end of the lever or detent 10, provided for that purpose with the slot 10 therein. Said lever 10 is pivoted as indicated at 11 and the end of the opposite arm 12 thereof extends within a slot 13 of the lever 27 of the replenishing mechanism, as shown in Fig. 11, to thereby lift the same into the path of the projection 1,6 upon the weft hammer-17, pivoted at 18, and operated in any usualmanner so that in the motion thereof to the left, viewing Fig. 11, the lever 27 will be moved bodily in the same direction. Said arm 27 is pivoted at 15 to the lever 15 the transfer shaft 27 of the replenishing mechanism. Through the described connections the transfer shaft 27 is rocked when substantial exhaustion of the filling in the running shuttle occurs and thereby through any usual ,or preferred mechanism the bobbin in the running shuttle is ejected and a new bobbin substituted therefor. \Vhile I have described in detail one method of operating the illustrated type of replenishing mechanism, it is to be, of course, understood that I am not limited to such form of mech- (see Fig. 11) mounted upon anism but that the replenishing mechanism may be operated in any desired manner upon filling failure or upon substantial exhaustion of the filling. At the replenishment side of the loom is provided the transfer lever 26, splined upon the transfer shaft 27 and adjustably secured thereon, as by a set screw 26. Also splined upon said transfer shaft is a lever 28, said lever being capable of longitudinal adjustment upon said shaft and adapted to be held in the desired position of adjustment as by the set screw 28. For convenience of description I have herein designated said lever as the primary lever for the cutter. Said transfer lever and primary lever extend essentially parallel and toward the lay and are united at their forward ends by a bolt 29, passed through hubs 29 of said levers and having at its other or screw-threaded end a nut 30. Between the hubs 29, 29 is mounted a sleeve 31, having an arm 32 provided, if desired, with a roller 33 thereon, said arm 32 forming in effect an extension of the lever 28. It will be seen that the levers 26 and 28 are by the described. construction rigidly united. Inasmuch, however ,s it is desirable to mount the filling cutt... at the selvage or substantially thereat and to aline therewith the operating means therefor, it becomes necessary, when weaving narrower goods, to shift the primary lever 28 for the cutter longitudinally upon the transfer shaft 27 to aline the same with the new position of the filling cutter. To do this, the nut 30 is removed and the lever 28 is moved to the desired position of adjustment, preferably leaving the transfer lever 26 in the position shown. The

nut 30 will then be replaced upon the exposed end of the bolt 29 so as to clamp the sleeve 31 against the hub 29 of the primary lever 28.

As previously stated, I mount the cutter for the filling close to the selvage, or it may be mounted in contact therewith, so that after the severance of the filling, whether new or old, essentially no exposed end of the filling is left at the selvage, the end 78 of the filling within the shed withdrawing into the cloth owing to the beating up action of the lay so as to leave issentially no exposed portion and to be essentially flush with said selvage. The relation of the end of the filling within the shed to the selvage is substantially illustrated in Fig. 4, wherein it will be observed that essentially no projecting end is exposed at the selvag. In using the ex pression essentially no projecting end is ex posed at the selvage, I intend to indicate a condition of affairs wherein the selvage is by the action of the cutter rendered esscntially free from exposed ends or, in other Words, a condition wherein the selvage does not need retrimming. In certain aspects of my invention, I am not however, limited to cutting or severing the filling at or essen tially at the sclvage.

In the present embodiment of my invention the filling severing means is a cutter and is mounted upon the lay and I employ such cutter shown to sever boththe old and the new filling, although as n'eviously stated, in certain embodiments of my invention the smile filling parting means or cutter need not l)v employed to sever both fillings, nor need if be mounted upon the lay. The said cutter is preferably mounted at the rear of the reed or at the rear of the plane of the front face of the rec-d, and in operation is projected to 'ough an opening of the reed into the pct! of the filling to be severed. ll located benx-ul the end of the reed, the cutter operates past such end or transvcrsel v thereof. In rder to accomplish this result. I provide a cutter carrier 4-7. pivotally mounted at 4r upon the lay, and preferably at the rear face thereof upon a bracket 35 to be more i'u v described. At or near the upper end of tie cutter carrier a re provided two cutting bl les or jaws 49, preferably essentially paraiiel and preferably of spring metal. I preferably incline slightly upwardly and in--ar llv or toward each ther the cutting edges of these knives, as indi catcd at 49'. .il ounted to coiiperate with said cutting blades or jaws 49 is a lower blade or jaw 43. carried at or near the upper end of a rod or slide 41, preferably having an enlargement ii at the lower end thereof. In the upward movement of said cutter or jaw 43. as will he described, said jaw tends to slightly furiher separate or force apart the jaws 43) and in so doing secures an ellee five out. If desired, one of the jaws 49 may be replaced by a guide to hold the remaining upper cutting jaw in correct position. While I have described the cutting edges of the jaws 49 as preferably inclined upwardly, I may instead incline upwardly or downwardly the cutting edge of the jaw 43 or h I may, if desired, provide flat cutting edges although the same would not be as effective as the lescribed construction. IVhether one "posite the or two upper cutting a ws be provided, I may deflect or.incline inwardly the upper cut ting jaw or jaws so that the same over-- laps the lower blade or jaw at the period of contact with each other. llpon the upper end of the rod or slide 41 is provided a pin 4%. and upon the cutter carrier 47 is a. pin 46. To these pins is attached the coil spring 45, the tendency of which is to hold the rod or slide 41 in its lowered position and hence to hold the cutter jaw 43 in its lower or non-cutting position. Iret'erably upon the under side of the lay is mounted by a screw 35, a bracket 35 carrying a pivot 3-5, whereon mounted a lever 34 which I have here shown as a cam lever and, for convenience of description, have so dcfined it, although it is to be understood that the said lever need not have a cam portion thereon. and other operating means may be substituted for said lever. Said cam lever 34 is connected by a pin 37 passing through a hub 36 thereon, with a sleeve adapted to slide upon the extension or lower end 39 of the sl de or rod 41. Said extension 39 has threaded upon its lower end the nut 40. ()wing to the relative location of the pivot 35 of the cam lever, the pivot 48 of the cutter carrier and the connection between the cam lTver and the rod or slide of the cutter blade or jaw 43, it will be observed that upon the forward motion of the lay the arm 32 of the primary lever 28 will impinge against said cam lever 34 at a point somewhat forward or to the left of the point of contact shown in Fig. 7 and will move said cam lever 34 upwardly upon its pivot, thereby sliding said sleeve 3 upwardly upon the extension 3.) and at the same time swinging the cutter carrier forward upon its pivot 49, so as to project the jaws of the cutter through the opening of the reed as shown in said Fig. 7. The said upward movement of the cam lever 31 brings the sleeve into contact with the enlargement 42 upon the slide 41 and thereupon the jaw 4-3 is brought into cutting relation with the upper jaws 49 as shown in Fig. 9. Said jaws 49 are preferably mounted as by a pin 50 upon a projection at the upper end of the cutter carrier. as indicated in said Fig. 9

The cam'lever 34 is preferably normally held depressed by the action of a coil spring 56, one end of which is securedin the hen ring 57, and the other end of which is secured in the hub 58. fast upon a shaft 35, to which the hub of the cam lever 34 is pinned. 2. shown in Fig. 10. Ifpreferred, the weight of the parts'may be relied upon to restore them to normal position.

Assuming substantial exhaustion to have en indicated at the side of the loom ooreplenishing mechanism. the transfer shaft 27 will be rocked and esscuti'ill'v upon the completion of the ensuirur forward motion of the lay, the transfer will take place by the ejection of the spent bobbin and the substitution therefor of a filled bobbin. In order to insure the correct operation of the parts, it is desirable that the filling contained upon the bobbin to be ejected should be severed by the cutter prior to the actual. transfer, that is, upon the same forward motion of the lay when the transfer occurs and preceding the actual transfer, so that when the transfer takes place and the old bobbin is ejected the filling thereof will be already severed and therefore such severed end may be withdrawn by the bobbin from the loom. I am not. however, to be limited to such period of severance of the old filling. I have so connected the cutter shown by me as that such described operation takes place.

I will now describe the means for severingthe new filling. I have providedan auxiliary weft fork 24 (see Fig. 3) that is a weft fork (or its equivalent) preferably upon the replenishing side of the loom, cooperating with the grid 23 and it will be apparent that upon the described forward motion of the lay, the old filling having been severed by the cutter at the selvage, on the replenishing side there will be presented to the said auxiliary fork at such forward movement of the lay, no filling. The result will be that said fork will not be tilted as in the normal operation of the loom at each alternate forward movement of the lay, and therefore the rear end or 100) of the said fork will not be lifted out 0 engagement with a hook 17" of the weft hammer 17. T herefore, in the further operation of the loom the weft fork slide will be moved and will impinge upon the up per end of the transfer lever 26, upon the transfer shaft 2", at the replenishment side of the loom, to thereby rock said shaft and again lift the primary lever 28 for the cutter so that upon the next forward movement of the lay the arm 32 of such lever will againbe in position to operate the cam lever 23% to again project the cutter within the path of the filling and to operate said cutter upon such forward movement of the lay. At said forward movement of the lay the shuttle containing the new bobbin will have been thrown to the opposite box or that upon the indicating side of the loom and hence one pick of filling from the new bobbin will have been laid in the shed, such filling extending from the spindle of the hopper, past the notch upon the hopper body, and thence to the thread guide or holder and then to the selvage and within the path of the cutter when the second time projected through the reed as described. In this manner the new filling will be severed at the selvage. Whenever filling is severed, whether new or old, a short piece thereof as indicated. at 77 in Fig. ft is cut by the action of the jaws and is subsequently discharged. In using the term auxiliary .veft fork I mean simply a device upon the replenishing side of the loom to detect the presence or absence of filling and it has no necessary connection with the weft fork upon the other side of the loom, if such be employed.

It will be apparent from the foregoing that when the filling is severed it is nearly at the completion of the forward movement of the lay, and that therefore such filling is held between the nearly closed upper and lower shades of the shed, and just in front of the reed, so that the said filling cannot escape the action of the filling severing mechanism.

At 7 in Fig. 2, I have indicated the old filling and at 75, in Fig. 3, the new, the filling 76 in Fig. =1 being either the new or old. At 53 is indicated the woven cloth and at 51 and 52 the upper and lower shades respectively of the shed.

At 59 I have indicated the shuttle feeler, the function of which is, as well-known, to determine whether the shuttle is properly positioned in the box and, if not, to prevent replenishment. It sometimes occurs that, although the shuttle is not quite correctly boxed, the shuttle feeler will work past the tip of the shuttle inasmuch as the motion of the feeler being normal to the axis of the shuttle and hence encountering the curved nose thereof, it acts to force its way past the same and cut the filling although no replenishment occurs. In order to avoid this result, I mount the shuttle feeler so that the same travels in a plane inclined to the path of travel of the shuttle when in running position, as shown in Fig. 3. The shuttle feeler is pii'oted at 62 and has thereon a pin 86 beneath which engages an arm 87, hung at 88 upon the transfer lever 26. Said arm 87 is provided at the rear end with a hook, with which is engaged a spring 89, suitably connected at its other end to any convenient part of the loom so that when the contact face of the shuttle feeler encounters the shuttle when not properly boxed, the lever 26 is prevented from fully rising, thereby preventing replenishment. Car'ied upon the shuttle feeler is an arm 91, extending toward one side of the loom as shown in Fig. 3, and cooperating in the well-known manner with a pin 92 upon the dagger to, when necessary, place said dagger in such position relative to the hunter 85 on the lay (see Fig. 14) that the replenishment may not occur unless the shuttle is properly boxed.

Although cutters have been devised to sever the old filling that is to be ejected, it not infrequently happens that, while the nearly empty bobbin is ejected from the loom, the severed end of such old filling will hence will not be withdrawn from the eye of the shuttle. If, therefore, such clamped end of the old filling (being still retained in the shuttle eye) retains an unbroken connection with the remnant of filling left upon the ejected bobbin, when the shuttle is replenished with a filled bobbin and is picked to the opposite side of the loom, there will be drawn into the shed not only the new filling but also the remnant of the old filling or a portion thereof, because the same was not withdrawn from the shuttle eye, although severed, thus forming a double pick. Thus, it" the ejected bobbin has considerable filling thereon, and this filling not snapped. betweenthe shuttle eye and the ejected bobbin as it isthrown into the can. then an entire pick of old filling will be drawn into the shed, to form a double pick it such old filling be caught between the shuttle and the box or binder. If, however, the old filling be so clamped between the shuttle and the box or binder and is snapped between the shuttle eye and the ejected bobbin in the can, then a trailing end (being an incomplete pick) is drawn into the shed with the pick of new filling. It will thus be seen that although cutters have been devised to sever the old filling yet not infrequently such old filling was immediately after. and upon the next pick, again carried into the shed. It has been largely supposed that the carrying of the old filling again into the shed was due to the fact that the cutter had failed to operate and that the old filling had not been severed, but I have discovered that the true reason is that the end of the filling is as described caught. usually lit-tween the shuttle and tinshuttle wall, and again carried into the shed. in rder to raw/exit this occurrence 1 have (2 l an ay a. portion of the from wall. of the s -:llc box. as shown at Fig. H, (which may or may not be provided with a leather or o1 her lining; such cut away portion extending atong such part of the shuttle box wall as muounters the shuttle. or preferably from about the eye 1 tiniuttle back to about its center. a mine the shuttle to ha i e la -o properly how-d. and also preferably at th lower portion of such wall. inasnnn'll as l have found that it is at such point that the end of tie filling is apt to be (:llltlllf. and clamped. With thi construction the severed end of the filling per mill d to escape from lhe shuttle with the ojw'ttwl liolllfdll.

In Fig. it I have shown the binder at the rear of the box. \idutl with binders at the front of the box and in such instances I recess a. portion of the binder for the same purpose as shown 1n Certain looms are pro@ Fig. 15. I may employ any desired type of binder. If in any manner, or at any time, the old filling, after being cut, is caught between the bottom of the shuttle and the box plate, or elsewhere, and thereafter is drawn into the shed with the new filling, both the new and the old filling will be simultaneously out by the cutter. Heretofore, so far as I am aware, no provision has been made for guiding the new filling between the replemshing mechanism and the selvage of the fabric. It frequently, therefore, happens that such new filling is drawn into the box or into the path of o era ting parts of the loom and is broken. 0 avoid this, I have mounted, preferably upon the forward portion of the shuttle box wall or hinder, a guide 65, having a. cam face (55 and having a recess 67 therein, into which the new filling will be drawn upon the first pick after replenishment from the weft replenishing side and thereby is guided along the upper edge of the shuttle. feeler so that-the filling cannot be broken by the shuttle feeler. The filling is thus kept out of the box and out of the way of the operating parts outside the box and is guided or held in position to be cu. Said. guide may be secured upon the shuttle wall in any desired position by the screw 66.

The shuttle feeler 59 is, as indicated in Fig. 13, rounded at the upper and lower portions of its forward end so that in the forward movement thereof to feel for the shuttle, the same will pass over the old filling and under the new filling and not interfere therewith.

Having thus described my invention and one embodiment thereof, I desire to state t'lai) the terms employed by me are used in their general sense and not in their specific nature and that 1 am in no wise to be limited by such language but that the scope of my invention forth in the claims. as follows:
